APPARATUS FOR REGISTERING TELEPHONIC CALLS- Specification of Letters Patent.

Patented May 7, 1907.

Application filed June 17, 1905. Serial No. 265,643-

To all whom it may concern.-

Be it known that I, DAVID FRANKLIN STAKES, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Registering Telephonic Calls, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to im rovements in telephone call registering an recordin instruments. In such instruments it has een customary to provide means at. each subscribers station whereby each call is registered and the number thus registered visually displayed. In systems where such instruments are used it is desirable that means he provided whereby at any time the central station may obtain an automatic record of the number of calls which have been registered at any given subscribers station at any given time.

Accordingly my present invention relates more particularly to means whereby the central station may at any and all times obtain an automatic record of the number of calls thus registered at each subscribers station, in combination with means whereby said record automatically records the phone number of the particular subscribers station in conjunction with the number of calls there registered, thus avoiding the possibility of mistake, which not infrequently results when as heretofore it is necessary for the operator to write down the phone number on the record otherwise automatically made of the number of calls there registered.

In the accompanying drawings, Figure I is an elevation of an instrument embodying my invention, the outer cover thereof being removed. Fig. II, is a section of the same taken on the line II, II, of Fig. I. Fig. III, is a plan view of the recording carriage. Fig. IV, is an elevation of the same from the oposite side from that shown in Fig. 1. Both igs. III, and IV, are on an enlarged scale. Fig. V, is a wiring dia ram of a telephone circuit conveniently inc uding a registering instrument constructed in accordance with my invention.

The registering apparatus pro er forms no part of my resent invention an I will thereore descri e it briefly. It comprises the sectional roller 1, mounted for rotation upon the stationary shaft 2. This roller comprises the sections or cylinders 8, 9, 10, and 11, the latter being rotated step by step, by means of the lever 3, having the pawl 4, which engages the ratchet wheel 5,. on the unit roller section 11. The lever 3, is normally maintained at one end of its throw under the tension of the coiled spring 6. In order to obtain a call, the subscriber must manually shiftthe lever 3, in opposition to the pawling mechanism will rotate the unit roller section 1 1, the extent of one tooth of its ratchet wheel 5. The cylinders 8, 9, 10, and 11, are interiorly geared according to the well known decimal system and have digits displayed upon their peripheries in such way as to exhibit, throu h a slot 13, in the frame of the a paratus, t e digits which manifest the num er of calls made by the instrument. In addition to the means thus described for visually dis laying a number corresponding to the num er of registered calls, the cylinders 8, 9, 10, and 11, are also provided with peripheral flanges 12, varying in width and position, and so arranged that the number and position of the flanges protruding from the lower side of the cylinders at any given time corresponds (according to say the Morse system of notation) with the numbers visibly displayed through the slot 13, on the upper side of the instrument. It therefore results that if a recording carriage provided with a movable contact be progressed immediately beneath the cylinders, the flanges will operate the contact to produce a telegraphic record of the number registered. The remainder of the ap aratus has for its object the production of t 's record, together with a simultaneous record of the phone number of the instrument from which the registration record has been taken.

On the lower side of the apparatus is fixed a plate 15,. provided with long and short cross-ridges l6 properly spaced tocause a movable contact traveling over them to re ceive contacts corresponding to the permanent phone number of the instrument to which the registering apparatus is attached. The shaft 20, is provided with a,spiral groove 21. A coiled spring 22, surrounds it at one end and tends to rotate it in one direction. Upon the same end of the shaft is set the tension of the spring 6, and in doing so,

a pinion 23, which meshes with a segmental. 'gear 24, which maybe rotated by the handle 25, to turn the shaft in the direction opposed to the tension of the spring 22 this rotation being limited in extent by the traverse of the carriage as will be hereinafter described. When the shaft 20, has been thus turned in opposition to the spring 22, it will reverse itself when released, but in order to prevent the escapement whee and which thereby the slows down the reverse rotation of the shaft.

Surrounding the shaft 20, and carried by it is a recordin carriage 31, its lateral motion upon the s aft being further guided by the fixed guide rod 32., which aso passes through it. This carriage 31, is provided with two sets of electrical contacts, one mounted on either side thereof, both of which are in mulitple in the recording circuit. One of these contacts is controlled by the plate 15, as the carriage passes from the right hand to the left hand of the instrument, as seen in Fig. I, and effects a record at the central station 57, which is indicated below thebroken line,58, in Fig. V, of the permanent phone number of the subscribers instrument 59, included above the broken line 60, in said figure. The other of these contacts is controlled by the flanges on the lower side of the registering cylinders. This is inoperative during the first traverse of the carriage, but during its return traverse operates the contacts so as to record at the central station, in immediate juxtaposition to phone number, the number of calls registere I will first describe the phone number recording contact which is mounted upon the side of the carriage seen in Fig. I. In this 33, is the fixed contact, and 34, the movable spring contact. A bell crank lever 35, is pivoted upon the corresponding side of the carriage and one arm of this lever carries an adjustable screw 36, which, when the lever is thrown, presses the spring contact 34, against the fixed contact 33. The bell crank lever 35, is normally maintained in the position of the drawings, by the spring 37. The other arm of the lever carries a swinging tappet 38, the lower point of which travels in immediate proximity to the plate 15. A stop 39, limits the motion of the tappet in from right to left the tappet causes a movement of the bell crank-lever corresponding to a 42, is a bell crank lever carrying the adjustable screw 43, which, when the lever is moved in one direction, presses the spring contact 41, against the fixed contact 40. The normal position of the bell crank lever 42, is determined by the spring 44. It carries a swinging tappet 45, the movement of which is'limited by a stop 46. When the carriage is moving from the right to the left of the apparatus as seen in Fig. I, the tappet is free to pass the flanges of the registering cylinders without causing any movement of the bell crank lever, but upon the return motion, by reason of the stop 46, these flanges cause a movement of the bell crank lever correspond ing to the flanges with which the tappet has come in contact during its return traverse. The contacts 33, and 34, are immediately connected with the insulated wires 50, and 51, which are also connected in multiple by the cross wires ,52, and 53, with the contacts 40, and 41, upon the other side of the carriage. The wires 50, and 51, are respectively connected with the line wires 54, and 55, of the telephone circuit extending to the central station where there is provided an ordinary recording instrument 65-, as shown in Fig. V. When it is desired to know at the central station just how many calls have been registered against any given subscriber upon lllS registering instrument, the sub scriber is requested to give the lever 25, a turn and then release it. As this is done the recording carriage passes first to one end of the apparatus and then back again. During the first traverse of this, movement there is recorded by the instrument 65 at the central station the permanent phone number of the ICC instrument, and during the second or return traverse a similar record is made of the number of calls which the instrument has registered. In this way the central station is enabled to obtain at any and all times an automatic and permanent record of the exact number of calls registered at any subscribers station, this record automatically including the phone number of the instrument.

Although I have shown a convenient embodiment of my invention it is obvious that many variations are within its fair scope. Thus the mechanism for producing contacts to indicate the number of the instrument one direction, so that as the carriage passes may be much varied, It is immaterial whether the operation of this means occur during a portion of the same traverse by which the record of the registered number of the registered calls is obtained, or during a reverse traverse, and if the latter it is immaterial which recordof the phone number or of the re istered numberis made first.

When I speak here and in the claims of the phone number of the instrument it will be understood that I refer to any arbitrary number or symbol by which the instrument may be identified.

Having thus described my invention, I claim 1. In a telephone call registering and recordingv instrument, comprising registering means; the combination with means arranged to record, at any time, at the central station, the number of calls thus registered; of means arranged to record at said central station the phone number of the instrument; means arranged to shift said recording means; and means arranged in co-operative relation to said recording means whereby the latter upon movement in one direction records the number of the phone, and upon movement in the opposite direction, records the number of calls.

2. In a telephone call registering and recording instrument, comprising means for registering calls, the combination with a traveling carriage provided with relatively movable contacts; of a circuit including said contacts and comprising a recording instrument at the central station; a rotary shaft upon which said carriage is mounted to move longitudinally; means in co-opera 'tiverelation to said carriage whereby the contacts are engaged and actuated to successively record at the central station the phone number of the instrument and the number of calls registered therein; and means arranged to rotate said shaft to shift said carriage into engagement with the contact actuating means, substantially as set forth.

3. In a telephone call registering and recording instrument, the combination of a registering cylinder with flanges corresponding at all times to the number registered by the instrument an interrupting plate ridged to indicate the phone number of the instrument; a carriage capable of moving in proximity to both the registering cylinder and said plate; an electrical circuit including a recording instrument at the central station; two sets of contacts mounted upon the carriage in multiple in said circuit; means whereby the carriage may vbe reciprocated; and means whereby during said reciprocation said contacts are successively operated by the flanges of the registering cylinders and the ridges of the interrupting plat-e, or Vice versa, substantially as set forth.

4. In a telephone call registering and recording instrument, the combination of a registering cylinder; an interrupting plate provided with means for indicating the phone number of the instrument; a carriage capable of moving in proximity to the registering cylinder and said plate, and having contacts; a circuit including said contacts and comprising a recording instrument; means in co-operative relation to said carriage Where by the contacts are actuated to successively record the phone number of the instrument and the number of calls registered therein; and means arranged to shift said carriage into engagement with said contact actuating means.

5. In a telephone call registering and recording instrument, the combination of means for registering calls; a traveling earriage provided with contacts; a circuit ii1 eluding a recording instrument at the central station, and com rising said contacts; means whereby when tlie carriage is moved in one direction, the contacts are closed in accordanee with the registered calls; and an interrupting plate indicating the number of the phone by which, when the carriage is moved in the opposite direction, the contacts are closed so as to indicate the number.
